Describes a unit that gives students an opportunity to write while actively exploring the scientific concept of magnetism. Provides students with a framework for recording their learning and gives teachers a method for observing how well students actually understand and can apply the knowledge they acquire. (JRH)

This book contains hands-on science laboratory activities for grades 4 through 9 that use discrepant events to challenge students. All of the "puzzlers" are based upon science principles and include directions for building gadgets that explain the "puzzlers." Topics covered include: volume conservation, magnetic phenomena,…

Opportunities to learn and discover surround a young child every day. The activities and ideas within this book have been formulated to encourage a child's natural curiosity and sense of wonder and to engage all the child's senses in learning and discovery. The activities focus on the child as a natural explorer and involve children in identifying…

This publication presents the background, support documents, and the accompanying 16 units needed to teach electricity and magnetism to fifth grade students. Included are materials lists, a discussion of the use of process skill terminology, a list of unit objectives, a vocabulary list, background information for teachers, and the 16 units. Topics…

THIS TRIAL EDITION OF A TEACHER'S GUIDE, BOOK TWO IN A SERIES OF FOUR, IS INTENDED TO PROVIDE RESOURCE MATERIAL FOR AN INTRODUCTORY STUDY OF ELECTRICITY AND MAGNETISM. IT IS SUITABLE FOR ADAPTION TO VARIOUS LEVELS FROM GRADES 2-10. USED IN CONJUNCTION WITH THE OTHER VOLUMES, IT PROVIDES MATERIAL FOR A PROGRAM OF FROM 5 TO 40 WEEKS, DEPENDING ON…

Describes an undergraduate physics experiment for studying Curie temperature and Curie constant of a ferromagnetic material. The exchange field (Weiss field) has been estimated by using these parameters. (HM)

A magnetic multipole apparatus suitable for the physics teaching laboratory is described. The apparatus enables the student to measure the magnetic field configuration of a single large coil, and of systems of one or more small coils. (Author/DS)

Described is a laboratory experiment in measurement of electrostatic potentials to help students gain an idea of potentials, which will provide a basis for deeper understanding of electricity and magnetism. The theoretical potential in this report is derived by taking into account the boundary of the actual experimental setup. (Author/DS)

Three activities involving electromagnetism are presented. Discussed are investigations involving the construction of an electromagnet, the effect of the number of turns of wire in the magnet, and the effect of the number of batteries in the circuit. Extension activities are suggested. (CW)

Presents low-cost learning activities to help teach elementary students about the earth's magnetic field. One project has students make a model of the earth's magnetic field. Another has them experiment with magnetism. (SM)

Studies magnetic oscillation using an air track. Ceramic magnets are attached to the cart and also are used as dampeners in place of the springs. The resulting oscillations are fairly sinusoidal and is a good example of simple harmonic motion. (MVL)

Technology for Science is a National Science Foundation funded program that is developing and testing curriculum units for teacher materials built around a series of design-oriented science problems called "challenges," mainly for ninth-grade general and physical science classes. Technology for science challenges have a clear connection…

Background information, lists of materials needed and procedures used are provided for 16 simple experiments on electricity and magnetism. These experiments are organized into sections dealing with: (1) Edison's carbon experiments (building a galvanometer, investigating the variable conductivity of carbon, and examining the carbon transmitter…

Describes an experiment based on Faraday's one-piece generator, where the rotating disk is replaced by a cylindrical permanent magnet. Explains the apparent paradox that an observer in an inertial frame could measure his absolute velocity. (GA)
